What exactly are the pizza, movie theater, grocery and convenience store industries trying to hide?

In 2010, a federal law was passed to get chain food establishments to provide calorie counts on menus and menu boards. That law makes good sense. Who can tell that a cinnamon roll (510 calories) has more than double the calories in a glazed donut (220), or that a typical tuna salad sandwich has almost 50 percent more calories (720) than a roast beef sandwich (460)?

But now the pizza industry, along with the movie theater, supermarket and convenience store industries, are trying to exempt themselves from and weaken this labeling law -- even though many Americans regularly purchase pre-made meals from these outlets. Under Texas Representative John Carter’s self-servingly named, "Common Sense Disclosure Act of 2012" (HR 6174), supermarkets, convenience stores and movie theaters would not have to post the calories for their prepared foods at all, and pizza chains would only have to list “calories per serving.” That's a real problem since a "personal-sized" pizza can actually contain four servings! How misleading is that?

Any industry that’s afraid to share basic nutritional information with you probably does have something to hide. But Americans deserve that information to allow them to make their own decisions about what to purchase and eat.
